Description
The 2 Motor Drivetrain Gearbox - Through Bore is compatible with the REV ION System and can be mounted in a variety of options, including flush with tube or spaced away from the tube to enable both chain in tube and chain/belt outside tube designs. The user can adjust speed by switching pinion gears on the motor between 10T, 11T, 12T, or can adjust wheel size by switching 2nd stage gear pairs. 2 Pairs of 2in pitch #10-32 tapped holes are available on output shaft for mounting the REV Through Bore Encoder, and mount holes for the gearbox are on the same horizontal plane as the output, set 4 inches apart. The output shaft is 1/2in Hex through bore, and output gears have a MAXSpline bore.
Selecting a Base Kit, Gear Ratio, and Speed Option are all required to assemble a gearbox. Motors not included.
